Submitting checkbox values from a HTML feedback form

[garion1]

I have tried a few tutorials on the web, but cannot get the checkboxes to work. I have the following HTML form:

<form method="post" action="contact.php"> 
<table width="600" align=left> 
<tr>
  <td width="62" class="bodytextbold">Name:</td>
<td width="377"><input name="Name" class="bodytext" size=50 maxlength="50"></td>
 </tr> 
<tr>
  <td class="bodytextbold">Email:</td>
<td><input name="Email" class="bodytext" size=50 maxlength="50"></td>
 </tr> 
<tr>
  <td class="bodytextbold">Company:</td>
<td><input name="Company" class="bodytext" size=50 maxlength="50"></td>
 </tr> 
<tr>
 <td class="bodytextbold">Phone:</td>
<td><input name="Phone" class="bodytext" size=50 maxlength="50"></td>
 </tr> 
 <tr>
 <td class="bodytextbold">Installation:</td>
<td>
  <table class="bodytext">
  <tr>
  <td>Building new house:</td>
<td><input type="radio" name="Installation" value="New"></td>
  <td width="25">&nbsp;</td>
<td>Existing house:</td>
<td><input type="radio" name="Installation" value="Existing"></td>
  </tr>
  </table>  </td>
 </tr> 
 <tr>
 <td class="bodytextbold">Preferences:</td>
<td>
  <table class="bodytext">
  <tr>
  <td>Home theatre:</td>
<td><input name="Preferences[]" type="checkbox" value="Theatre"></td>
<td width="25">&nbsp;</td>
<td>Distributed Audio and Video:</td>
<td><input name="Preferences[]" type="checkbox" value="Distributed"></td>
<td width="25">&nbsp;</td>
<td>Home Automation:</td>
<td><input name="Preferences[]" type="checkbox" value="Automation"></td>
  </tr>
  </table>  </td>
 </tr> 
<tr>
  <td valign="top" class="bodytextbold">Message:</td>
<td><textarea name="Message" cols=50 rows=5 class="bodytext"></textarea></td>
 </tr> 
<tr>
  <td colspan=2 align=center><input type=submit name="send" value="Submit">&nbsp;&nbsp;&nbsp;<input type="reset" name="Submit2" value="Reset"></td>
 </tr> 
 </table> 
</form>

And I have the following PHP file (contact.php):

<?php 
$to = '[e-mail]' ; 
$from = $_REQUEST['Email'] ; 
$name = $_REQUEST['Name'] ;
$headers = "From: $from"; 
$subject = "Website Contact"; 
$fields = array(); 
$fields{"Name"} = "Name"; 
$fields{"Company"} = "Company"; 
$fields{"Email"} = "Email"; 
$fields{"Phone"} = "Phone"; 
$fields{"Installation"} = "Installation Type";
$fields{"Message"} = "Message";
 
$body = "You have received the following information:\n\n"; 
foreach($fields as $a => $b){ 
$body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]);
}
$send = mail($to, $subject, $body, $headers); 
if($send) 
{header( "Location: success.html");} 
else 
{header( "Location: error.html");} 
?>

The form works fine besides the checkboxes. I have removed the checkbox code from the PHP file as I cannot get it to work.

How can I get the output email to display which checkboxes have been checked?

I think the problem is that you are passing an array to sprintf. Try something like:

foreach($fields as $a => $b)
{
 if($a == 'Preferences' && is_array($_REQUEST[$a]))
 {
 $body .= sprintf("%20s:\n",$b);
 foreach($_REQUEST[$a] as $preference)
 {
  $body .= "> $preference\n";
 }
 }
 else
 { 
 $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); 
 }
}

I haven't tested this and you'll also need to add 'Preferences' into your fields array. I'd say that's the issue though.

The "method" on your form is "POST", this means that all your HTML elements that carry the data will be available in the SUPER GLOBAL $_POST.

eg.
$value = $_POST['HTML_element_name']

Therefor

The checkbox name "Preferences" will be passed in the SUPER GLOBAL $_POST or $_GET (If method "GET" is used) and will be an array of the "Preferences" values.

$cb_value = $_POST['Preferences'}; creates an array $cb_value.

You can the loop through the $cb_value array to discover the values

$i = 0;
$n = count($cb_value);

while ($i < $n) {
echo $cb_value[$i] . "\r\n";
$i++;
}

Hope this helps

Thanks for the help. I am not a PHP coder, so I will try and make sense of your posts.
I appreciate the help though.
